of Indiana, have invented or discovered new and useful Improvements inFiltration Sys tems, of which the following is a specification.

My invention consists of a new and irnproved filtration system for thesupply of pure Water from a stream or other'body of water. f

Itccnsists of sinking a well or wells in the bed of said body of water,casing off the same, so that the Water can enter saidwells only throughsuitabie straining means in the bottoms thereof, and leading the Waterfrom said wells by 4means of line-pipesunder the surface of said'body ofwater into a suitable reservoir, into Whichit is downwardly dischargedby means' of an inlet-pipe extending Within said reservoir to a pointadjacent to the bottom thereof. A By this means the pressure of verseratio to the height of water in said in let-pipe and the reservoir.

In the accompanying drawings, Figure 1 is a vertical section of the bedand bank of a ,river orother body of water, showing my system installed;and Fig. 2 is a diagram 1n plan of the same.

T h following 1s said drawings. e

1 is a river or other body of water, and 2 is the natural bed thereof,usually'composed of layers of sand and gravel, or either,l substantiallyas indicated in Fig. 1. Into this natiilter-bed I drive a plurality ofWells 3 3 to secure the required material, usually about thirty orfortyffeet. Said Wells are cased off by means of casing 4 4l, and 5 5are the usual stiainers inserted in the bottom of said cas'- ings. Ifind two-inch vcasing te be a cona detailed description of to theproperdepth thickness of filtering venient and satisfactory size andpreferably space my wells apart at least twenty-five feet to obtain asufficient area of filter-bed t0 sup ly the requisite quantity of waterto eac well. The casing 4 4 is led up into the body of water, and thatof each we is closed oi and connected by substantially horizontal pipes6 6 toa line-pipe' 7. l prefer to drive my wells in arallel lines, asshown in Fig, 2, and lay a ne-pipe 7 between adjacent lines of wells, asshown. Said line- 5 5 pipes 7 7 maybe laid on the bed of the river,

discharge is maintained in reas shown in Fig. 1, or may be otherwisesupported beneath the surface of the water,A

preferably not less than three feet beneath the same, as a sufficientdepthis required to drive the water through the line-pipes into thereservoir. By increasing the diameter of the line-pipes as they approachtheir discharge ends I am enabled to accommodate the increasing volumeof water from the Wells without difficulty. T his\ gradual in creaseindiameter is illustrated in the drawings. 8 is the reservoir or tankinto which said line-pipes 7 7 discharge below the level of the water inthe river. Said reservoir may be located on the bank of the stream., asshown, or in any other convenient positionas, for instance, in theriver-bed. It is preferably built up to a height sufiicient to preventthe river overiiowing into it in time of high water or may be closedover with a water-tight cover for the same purpose. Its bottom isconsiderably below the waterlevel ofthe river to provide the requisitecapacity, as the water-level of the river is the limit of waterlevel inthe reservoir.

It is evident that a continuous flow of filtered Water is securedthrough pipes 7 7, which enter vthe reservoir below the Water levelofthe river as long as the level of water in the reservoir is below thatof the river.

ends of line-pipes 7 7 Within the reservoir 8, eachg'arm of saidsections being preferably provided with gates 10 10, which arepreferably operatable-from without the reservoir by means of suitablemechanism 11. 11. 1 2 is an additional section of pipe attached to eachof the T's 10 10 and extending down wardly in the interior of thereservoir to a point adjacent to the 'bottom thereof. The oice of thisdownwardly-extending section `12 is to increase the pressure ofinflow-of water, as will be explained.

Assuming the levelof water in the reser voir to be reduced by withdrawalor other- 'wiseto a point below the level of the discharge end of ipe 7,a vacuum more or less perfect Will be ormed-in pipe 12 between the levelof Water standing in said pipe and the discharge end of pipe) 7. Iiiother words, the stream of water discharging from pipe 7 is thusreleased `lfrom the atmospheric back pressure, which ICO IOS

IIC

retically' for every twenty-seven inches of height in said void orvacuum the pressure of discharge is increased by one pound, so that thelower the level of water in said reservoir and the faster the same iswithdrawn there- .from the faster the water enters through pipe 7 andthe greater the pressure ci said entrance as long as suflicient Waterremains in the reservoir to form a water seal for the lower end of pipe12 to prevent the entrance ofatmospheric air. l

Themse of the gates 10 10 is asfollows: NormaPythe upper gate is closedand the lower gate open to admit the water to pipe 12. In case itiszdesired to clean the wells connected to a given line-pipe l7 thelower gate 10 is closed and the upper gate opened. A steam, air, orwater pressureline is now attached to the upper arm of the T 9 and aback pressure set 'up-in the line-pipe 7 and the connecting- Wells,whereby ,any foreign matter is quickly blown out of the same, By thismeans also any deposit of mud, silt, or other impurity may be blown awayfrom the bottom of the wells.

I prefer to connect the well-casing 4 4 at the top to the pipes 6 6 bymeans of T members 13 13, the arms of the T being set vertically, as inFig. 1 and the upwardly-extending arm being normally closed by a plug.By removing said plug it is evident access at all times may be gained-tothe interior of the wells for repairs to or replacement ofthe strainers5 5 or for such other purposes as may be required. l

lf the reservoir be closed over on top, as shown in Fig. 1, I providea'vent-pipe 14, leading up beyond high-water mark to prevent backpressure in the reservoir against the rising water-level. Theouttake-pipe is preferably led out of the reservoir at a level nothigher than the water-level of the river to preventsuction in the pumps,and the same is led down within the reservoir to a point adjacent to thebottom of the reservoir to permit withdrawal at anylevel. Said pipe ismarked 15.

lt is evident from the above that my system provides a complete,satisfactory, and automatici'iltering means wherein the natural bed ofthe river is used. A filter-bed. and the natural river-pressure'automatically delivers the water to the reservoir wherein it isdischarged at a pressure in inverse'ratio to the level of water in saidreservoir. The action is not forced, but natural, so that the Waterseeps through the filtering-bed, so that there is no suction or drawingin of foreign material into the supply. The mud and filth strained outof the water is deposited on top of the ilter-bed, whence it is washedaway by the next reshet, The system is capable of iniinite extension asneed requires, additional wells being sunk and line-pipes connected tothe reservoir as desired.

What I desire to cla'im is 1. A filtration system consisting of a wellin the bed of a body of water, a reservoir, a pipe leading the waterfrom said well into said reservoir below thelevel of said body of waterand a dischar e-tube connected with said pipe and exten ing downwardlywithin said reservoir, substantially as and for the purpose described.

2. A filtration system consisting of a well driven into the bed of abody of watervand cased up above the bottom thereof, a reservoir, aline-pipe beneath the surface of said body of water connecting said wellwith said reservoir and a discharge-tube connected with said line-pipeand extending downwardly within said reservoir to a point adj cent tothe bottom thereof, substantially as and for the purposes sel forth.
